"The improvedcnltivator comprises amain frameyhere shown asmade up of anintegral length of -material,such as-a rod The frame includes anupstanding yoke, 1, from the lower ends of ivhich the frame bar or rod'-;is-;pro'jecte'd laterally and-oppositely at 2,-ari-d then- 'rarwaraiyaes, and at the rear ,{e rrd each' length-E3 is armed to providean inward extending uhaped section 4.

of its length, but givena half turn throughout the rear portion, \toprovide a flat isection lO. A clip 11=is rotatably: mounted for verticalpivotal motion on the rear leg of each section 4, andtherear-end of thesection 10 vof each shovel beam is pivotally vconnected at12 forhorizontal pivoting with said frame. ilrrdeperrdent means are pro-.relation to the clip. The draft s hov'el beams are thus capable ofindependentvertical and horizontal movement. The forward ends ofisuchzbeam's are provided or, formed ivith .nguide members 13, eachreceiving one mem- OM18 r k 1, rollers 14','forming l?art are membersfor ape poses.

The guide members loosely engage 'the yoke sections, to permrtslim tedhorizontal and free {vertical movement of they beams 9; Shovels or othertools 15a re secured to the beams in any preferred manner.

The beams are arranged for vertical adjustment, either simultaneously orindependently,therebeing mounted on the draft bar 6, a 1ever16-above'e'ach -beam,-'the forward end of Whichlever is'connectedtotheparticular beam by-a linlrl i, This permits independent verticaladjustment of the-beams,

the play being on the bearings of clips 11.

'The simultaneous verticaladjustmentof the beams is provided for througha single lever 18 mounted on the draft-bar 6. 'Thefor ward end of thelever 18, is loosely connected to a lifting member 19,0f invertedU-form,

: prop riate point.

with oposite' laterally projecting terminals 20. The'vertical' bars 21of the lifting member extend through openings 22 in the beanis,

preferably formed by bars 23 connecting the beam and one of the shovelbars at an ap- V The termin alsj QQ serve to simultaneously lift thebeams ivhen the lever 18 is operated, the free play of the beams on thebars 21 of the lifting member, above the terminals 20, permittingindependent adjustment of the beams, when desired, through theappropriate lever 16. The lever 18 is preferably arranged to be lockedin adjusted position as by the dog-and-seg ment means 24, therebyproviding for adjusting the cutting depth of the tools at will.

The beams are also capable of lateral adjustment, each being connectedwith the adjacent frame bar 3, by a toggle lever 25, the joint of whichis connected to the forward terminal of a foot rod 26. This rod inclinesrearwardly and upwardly, and is slidably supported in a bracket 27,secured to the section 4 of the frame. The rod extendsupwardly in therear and has a lateral foot rest 28, whereby the rod may be operated.The normal positions f the beams break the toggle levers toward therear, so that either beam may be adjusted inwardly by pressure 011 thefoot rod. The guide members 13 permit the lateral movement of the beams,without interfering with the direct draft of such beams, this lateralmovement of the beams being of course on the pivotal mountings 12.

The frame is mounted at the rear end on ground wheels 29, the spindlesfor which are secured to the U-sections 4 of the frame. The forward endof the frame issupported on one side by a small wheel 30, the spindlefor which is extended upwardly at 31, and slidably mounted in a sleeve32 secured to the frame bar 2, a set screw fixing the adjustment. Theopposite frame bar 2 is prefs erably provided with a runner 33, whichthrough a spindle shaft 34, sleeve 35, and set screw 36, is adjustablewith relation to such frame bar 2.

A drivers seat 37 is supportedon a seat frame 38, the forward terminalsof which are looped about the forward ends of the U- sections 4 of themain frame. The seat is adjustable as to height, through sleeves 39,mounted on the uprights 5, and held in adjustable relation thereto byset screws 40. Eyes 41, carried by the sleeves, slidably receive thebars from the seat frame 38. i

The implement is tongueless, in that projecting part beyond the frame isnecessary for draft purposes. The draft connection includes a bar 42,secured by a link 43, to a pin joining the draft-bar strips. Pullbars44extend from bar 42, and are connected by links 45 with the frame bars2.

Ordinary single trees 46 are connected di rectly to the pull-bars asshown.

The shovels or other tools, are, in the present improvement, entirely infront of the driver, may be seen at all times and adjusted as necessaryto comply with conditions. The tools are wholly within the main frame,and in the absence of an extended tongue or the like, the structure as awhole may be readily turned or guided under circumstances where theusual devices of this class could not be used.
